1 Claim.

This invention relates to an elastic collar clasp.

An object of the invention is to provide a simple and eflicient meansfor mounting the springs of the device on the shanks of the jaw units,whereby a very useful device i produced.

Another object of the invention is the improvement of the' constructionof the elastic collar holder disclosed in my Patent No. 2,331,625,issued October 12, 1943.

A still further object of the invention is the construction of a holderdevice of this typ in which the grips on the shanks perform a dualfunction, to wit: First, they hold the springs on the shanks, andsecond, afford the means by which the operator manipulates the jaws onthe shanks.

With the foregoing and other objects in view,

my invention comprises certain novel construc-.

units in an extended position.

Figure 5 is a fragmentary, vertical sectional view of the device, shownin an extended posi'-.

tion.

Figure 6 is a perspective view of one of the jaw units.

Figure 7 is a perspective view of the tubular casing.

Referring to the drawing by numerals, l designates a tubularcasingpwhich is provided in its bottom with an elongated slot 2. Thereare two jaw units, each comprising a long, straight shank 3, which isprovided at its inner end with a depending right angled grip 4. On theouter end-oi shank 3 is jaw 5. Acoil spring 6 is mounted on shank 3between grip 4 and jaw 5.

The grips 4 are normally together and extend throughslot 2. Therefore,it will be'seen that the grips perform a dual function, to wit: Theyhold the coil springs 6 on shanks 3 and also serve as the operatingmeans whereby the manipulator can utilize the device.

It will be understood that the outer ends of the springs normally bearagainst the ends of the tubular casing l and when outward strain isexerted on jaws 5, the springs will be compressed, Fig. 5, and whenstrain, is relieved, the springs will move the grips inward until theyare in engagement as shown in Fig. 3.

The placing of the device on the collar is clearly illustrated in Fig. 1of my Patent No.f2,331,625, hereinbefore referred to. i

The foregoing described construction of the tubular casing, jaw unitsand springs produce a very compact and durable structure, which is adecided useful and novel improvement over prior structures.

While I have described the preferred embodiment of my invention andillustrated the same in the accompanying drawing, certain minor changesor alterations may appear to one skilled in the art to which thisinvention relates during the extensive manufacture of the same, and I,therefore, reserve the' right to make such alterations or changes asshall fairly fall within the scope of the appended claim.

What I claim is:

As a new article of manufacture, an elastic collar clasp, comprising atubular casing, provided with partly closed ends, having also anelongated slot in its side, said slot having its ends near the ends ofsaid tubular casing, a pair of jaw units, each jaw unit comprising anelongated shank, said shank slidably mounted on said partly closed end,said shank provided at its outer end with a jaw and at its inner endwith a right angularly extending grip, said grip extending through theat their outer ends the outer ends of said tubular casing, and saidsprings engaging at their inner ends only said right angularly extendinggrips.
